I was having the problem of not being able to save changes to events using Firefox and JCE, so I upgraded JCE to latest version. Now, when I go to edit an event, I can save, but there are NO jce editor buttons at all. I tried switching the global config to tiny mce, and those do show up. Moo tools plugin is enabled.
joomla 1.5
jevents 1.5.6
jce 2.0.20
